SPECIFICATION forming part of Letters Patent No. 297,252, dated April 22, 1884.

' Application filed March 21, 1883. x0 model.)

To all whom, it may concern:

Be it known that I, JOHN GARSED,0f Philadelphia, in the county of Philadelphia and State of Pennsylvania, have inveutedcertain new and useful Improvements in Stop-Motion Devices for Spooling'Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates more particularly to the stop-motion devices for spooling-machines patented to J. and T. A. Boyd, January 18, 1881, No. 236,767, although it may be adapted to other spoolingmachines. The stopmotion devices in the Boyd spooler consist in part of a series of light detector-levers pivoted in sets of four to brackets underneath a longitudinal rail,with their inner ends, which extend toward the driving-drum, provided with rubber pieces to increase the friction when brought in contact with the said drum. These frictional pieces, which consist of short sections. of rubber tubing, are slipped over the ends of the levers and should be retained close to the driving-drum without being in actual contact; but they are liable to drop off or work back on the levers, and require considerable attention on the part of the attendant to keep them in proper position for the driving-drum to act the instant a thread breaks or is exhausted from the cop or bobbin. In spooling yarn care should be exercised to keep the threads intact, especially where two or more threads of different colors are run onto one spool. Should one of the threads break and the detector-lever-fail to act or the attendant neglect it, theyarn from the remaining cops would still continue to pass onto the spool,while this one particular color would be left off and would tend to mar the finish of the goods when To correct this the attendant is obliged to remove all the yarn from the spool until the broken end is found. In my invention the india-rubber pieces or tips are adjusted by means of screw-threads formed on the detector levers or fingers and corresponding screw-nuts, so that they can be readily and accurately adjusted, and will so retain their proper position relative to the drivingdrum as toinsure prompt action on the breaking of a thread or upon the thread becoming exhausted from the cop or bobbin. I also employ a sheet-metal sleeve, which is passed over the-end of the india-rubber tube or tip adjacent to the screw-nut, for the purpose of closing the slot made at this end to accommodate the hooks or curls which are attached to the detector levers.

Reference is had to theaccompanying drawings, in which Figure 1 is a plan view of aset of detector-levers employed on the Boyd spooler. Fig. 2 is a plan view of the same, showing the india-rubber tubes or tips adjusted by means of my invention. Fig. 3 is a longitudinal section of my invention. Fig. 4 is a perspective view of one of the india-rubber tubes or tips, and also one of the sleeves used in my invention. Fig. 5 is an end elevation of the stop-motion as employed on the Boyd spoollug-machine, showing one of the detector-levers with my invention applied.

A A, Fig. 1, are the detector-levers, and B B are the india-rubber tubes or tips used, as stated, on the Boyd spooler. It will be observed that each tube or tip is provided with a longitudinal slot, 8, in one end to admit the hook or curl F, and that they are merely slipped over the ends of thelevers, depending upon the contraction of the rubber to keep them in place; but it has been found that they are liable to shift their position and frequently to drop off. The attendent is also liable to press them too far back on the lever for the drum to act.

The detector-levers A A, Fig. 2, in my invention are each furnished at the proper distance from the inner ends with screw-threads O and a nut, D. The screw threads can be formed on the levers before the nuts are put on; or the nuts themselves will cut the threads, owing to the fact that the levers are made of wood.

E, Figs. 3 and 4, is a sheetmetal sleeve made to slip over the slotted end of the india rubber tube or tip B, to close the slot 8 around the guide hook or curl F, and assist in retaining the tube or tip on the lever.

The nuts D are screwed onto the levers a proper distance from the inner ends of the same to accommodate the tubes or tips B, and after these are slipped on the nuts are adj usted so as to bring them all in line and present 5 the ends of the tubes or tips evenly to the driving-drum, in which position they will be retained to be acted upon should a thread break or become exhausted from the cop or bobbin.

1 do not Wish to claim, broadly, the detect- 10 or-levers or the indie-rubber tubes or tips on the end of the same; but

What I do claim, and desire to secure by Letters Patent, is

1. The combination of the detector-lever A,

I 5 provided with screw-threads G, with the nut and described.

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of March, 1883 JOHN GARSED.
